CC   -!- FUNCTION: Repressor involved in the biosynthesis of the osmoprotectant
CC       glycine betaine. It represses transcription of the choline transporter
CC       BetT and the genes of BetAB involved in the synthesis of glycine
CC       betaine (By similarity). {ECO:0000250}.
CC   -!- PATHWAY: Amine and polyamine biosynthesis; betaine biosynthesis via
CC       choline pathway [regulation].
CC   -!- SEQUENCE CAUTION:
CC       Sequence=ABA53008.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
